Kourtney Kardashian said bye-bye to baby fat.
The brunette beauty, showing off her svelte figure in a skimpy bikini on the cover of OK! magazine, revealed that she's lost 45 lbs. since giving birth to her son Mason last December.
"They say it takes a full year to really get your body back," she told the magazine. "I believe that. I was 140 pounds when I gave birth and I'm 95 now."
Kardashian said she stuck to a strict workout regimen and had frequent, portion-controlled meals to work off the baby weight. The "Keeping Up with the Kardashians" starlet even found ways to bring baby Mason along.
"I'd take him on walks when he was a baby and do squats while holding him," she said, according to the New York Daily News.
Still, Kardashian gives into her cravings once in a while.
"I'll eat Oreo Double Stufs, but I will have two instead of a whole box. And I love chips," she said.
